Restart SLA by running the below command as the root user: # pmtool restartbyid sla ------------------------------------------------------------ WORKAROUND STEPS FOR FIXED VERSION: ------------------------------------------------------------ After FMC upgrade to a fixed version, the user must remove the certificate file at /etc/sf/gch/call_home_ca and restart the Smart Licensing Agent (sla) process to resume communications with Cisco Smart Software Manager (CSSM) with these steps: 1. Access the CLI. For FMC deployments, log in to the FMC CLI as admin or another user with shell access. 2. Enter the expert command in order to access the Linux shell. 3. Elevate the user to root with the "sudo su" command and enter the password when prompted. 4. Remove the /etc/sf/gch/call_home_ca file with the rm /etc/sf/gch/call_home_ca command. 5. Restart the Smart Licensing Agreement process with the "pmtool restartbyid sla" command. ---------------------------
